Drought Indices

Drought is a costly weather situation in the United States that is of high interest to TV viewers. Droughts impact crop growth, water supply, and natural vegetation. Soil and vegetation conditions during drought create risks for wildfires and flash floods. Depending on time frame and situation, the relevance of the drought may differ, in that short-term rain deficits affect soil conditions and agriculture, while long-term droughts impact water reserves and can cause dust storms. Through several drought related products, broadcasters can convey an accurate representation of the drought risk to their viewers on a regular basis.
